LUBRICATOR.

SPECIFICATION forming part of Letters Patent No. 324,339, dated August 11, 1885.

Application tiled July 5), 1885. (No model.)

To all whom it may concern:

Be itknown that we, ROBERT BUDDY, of Mount Vernon, Westchester county, State of New York, and LEOPOLD KAOZANDER, of the city, county, and State of New York, have invented certain new and useful Improvements in Lubricators, of which the following is a specification.

Our invention is directed to lubricators intended more particularly for use with locomotives, and refers tothat class of lubricators known as drop-feed lubricators, in which water resulting from condensation of steam is used for the purpose of raising the oil to a certain height in the cup, whence said oil will be carried ott through a sight-feed77 tube` or glass into the steam-conduit, and thence to the parts to be lubricated.

Our object is to simplify as far as possible the construction of the parts,while maintaining the entire efficiency of the lubricator.

The nature of the improvement can best be 'explained and understood by reference to the accompanying drawings, in which- Figure I is a vertical central section of the lubricator on line 1 1, Fig. III. Fig. Il is a like section. Fig. Ill is a horizontal section of the oil-cup on line 3 3, Fig. I, omitting the sight-feed tube connections and the valve for controlling the escape of the water from the condensin -chamber into the oil-cup.

The oil' up is represented at F. It is cast in one with the tubular neck A, constituting the main steam-conduit, and with avertical and central channel, B, forming a straight continuation of that conduit and extending up to the top of the oil-cup, where it joins the d aphragm or partition that closes the mouth of the oil-cup, land forms the bottom of the condensing-chamber C, which latter is screwed into the neck ofthe oil-cup in the usual way.

Through the bottom of the condensingchamber is an opening communicating with the chamber H formed by the casting.

J is a second chamber, from which extends the pipe L to near the bottom of the oil-cup. Communication between the two chambers H and J is controlled by a valve, K. The parts H J K L are intended to feed the water of condensation from the condensing-chamber to the oil-cup, and are arranged and operated for this purpose in the manner described in United States Patent No. 316,834, of April 28, 1885.

The vertical chamber B terminates in a steampipe, D, screwed to the top of the said vertical channel, and extending up nearly to the top of the condensing-chamber C.

` This constrlction requires only avery short and easily-accessible steampipe, which is much easier to keep in order than the long steam-pipes screwed into the bottom of the lubricator, as heretofore generally applied.

Near the top of the steam-channel B, cast in one with it and with the oil-cup, is abranch ehannel,G, leading intothe upper connection, l?, of the sight-feed glass E.

Oil from the cup enters the lower sight-feed connection, O, through the pipe N, these and the remaining portions of the sight-feed devices being substantially the same as in the Letters Patent No. 316,834c hereinbefore referred to.

^ The operation of the lubricator is as follows: Steam from the main steam-conduit A passes through channel B and pipe D into the condensing-chamber G, and at the same time, through channel G, directly into the sightfeed glass E,which it fills with water. The oil displaced by the water enters thepipe N, and through it the lower connections of the sightfeed glass, passing through the nozzle G and glass E. The oil is conducted through channels P, G, and B back to the main steam-conduit A, and thence to the parts to be lubricated.

It will be seen by this description that the entire distribution of the steam to the condenser and to the sight-feed glass, and the conducting of the oilto the out et at A, is effected by one single channel, B.

It is to be remembered that the steam-channel B has no immediate connection with the oil-space of thelubricator, the only connection between the two being effected through the condenser C and parts H, J, and L.

Vhat we consider to be new and of our own invention is 1. The combination, with the oil'cup, the sight-feed glass, and its connections, of the main steam'eonduit A and the channel D, located Within and cast in one with the body of the oil-cup and extending vertically and centrally from the bottom to the top of the oilcup, having no direct communication with the oil-space of the lubi'icator, substantially as hereinbefore set forth.

2. The combination of the following instrumentalities, viz: the oileup, the sight-fced glass and its connections, the main steam-con duit A, the channel B, located Within and formed in one with the body of the oil-cup and extending vertically and centrally from the bottom to the top of the oil-cup, having no direct communication with the oil-space ot' the lubrieator, the condenserQand the steampipe D, screwed into the top ofthe channel B and forming its straight continuation to the upper part of the condenser, substantially as hei'einbefore set forth.

3. The channels B a1nlD,fo11ning one single Vertical steampassage through the oil-cup into the upper part of the comlensing'cham bei', the lower portion of which passage, located Within the oil-cup, communicates with the upper connection of the sight-feed glass by a horizontal branch channel, G, substantially as and for the purposes hereinbelore set forth.

In testimony whereof We have hereunto set our han ds this lst day of July, 1885.
